To (71/- (I'll 0711/ if 727/07,! concern:

' Be it known that 1, Lotus ANDRE NOEL, civil engineer, a citizen of France, residing at 52 Boulevard llaussnnuin, Paris, France, have invented new and useful improvements in Spring heels, of which the following is a specification.

, This invention relates to e spring-Wheel of uniform resiliency, the characteristic feature ofwhich consists in thespplicetion of spiral springs, all arranged to Work constantly and simultaneously in all directions and on all the coils, Whatever he the point of the folly which receives shock or impact.

The wheel consists of e telly-plate moving between two plates solid with the hub, hetween which are disposed spiral springs on which the-folly works, and the distinguishing feature is that the springs are placed outside of the ly-plnte in pockets suitslzly formed in the plates solid with the hula and that the inner ends of these springs are solid with axles fixed on the lolly-plate and hich projeet from. each side of this plate. With such a construction the folly-plate is extremely light, the springs lzeing outside this plate, and its ineitis is (GIY slight, which increases its sensiliwity, and therefore the eltisticilyof 'he wheel. On the other hand, the springs hear constantly at their outer coil in the re cesses in the side plates, and. as they have their inner coil solid with the axles carried by the central plate or folly-plate it will he understood that these springs are torced to work constantly and siinulteneo" j all it onetime in all directions and on all the coils either under tension or compression or r lling strain endlollowing all the redial direc tions into which they are brought hy the movement of the folly-plate.

In the annexed drawing, Figure 1 shows one-half of a wheel, partly in sectionend partly in elevation; and Fig. 2 is a longitudi nail section following a broken line to show the various details.

Referring to the drawing, the Wheel horn prises a. central plate (t, which carries the rim, and two side plates l) and 0, solid with the hub, rigidly connected together by the adjustable cross-pins a; and kept at a suitable distance apart to sllow of play from the central plate a 111 its plane.

I in the plates l) ends are the cylindrical l housings or pockets -v of errie-hie number and distributed over the whole surface of the said plates. In these pockets ere arranged the hat spiral springs 1, hearing at their outer coil in the said pockets.

The central plate a has fixed thereto corresponding to the pockets 1 axles or spindles f, which enter from each side the center oi these pockets and on which axles are fixed, the inner coils of he s rings r. ment is generally mm c by making the inner coil in the 'lOlHl of a cylindrical tube'which is engaged on the corresponding spindlef.

'l he construction is completed by the pro- Vision of perforations 0, formed in-the plate 0. for the free passage of the hub and the cross-holts 90 during the movement of the plate, and, it necessary, by the pecking y, hired on the plates 1) and c and intended to prevent mud and dust from penetrating between these plates and the central plate a.

It ill he understood that eech shock received by the rim causes the plate a to slide and by its spindles f to tighten all the spiral springs of which ell the coils contribute sirnultnneously to the cushioning effect and then to restore the plate (Z to its normal positior concentric W .ith the axle.

'l. is lightness and smell inertia. of the telly-plate are evident:

Heving new described my invention, whet l claim as new, and desire to secure by Lettors Patent, is-

1. A. spring-wheelcomprising in comhinntion a central. piste carrying; the lolly, twoside plates solid with the hub and provided with recesres or pockets formed therein, spiral springs located Within said recesses or pockets, axles or spindles fixed to the central plate, extending {Tom each side in the recess or pool-lets end on which are wed the inner coils ol the springs, end means For iiinin said recesses-oi;

This ettech- 5 fort recesses or pockets and on which are fixed I name to this specification in the presence-of the inner coils of the Isprings, esadjusltable 1 two subscribing witnesses. cross-b0 ts connectin t e twosi e ates, e 4 "1 and erforetions fornfed in the centrayplate i v 1 LOUIS ANDRE NOLL' iie free passage of the hub and the cross- Witnesses: bolts.
